EXGAVATOR FOR FLESHING DIVIDED COCOANUTS.

Specification of Letters Patent. Patented Oct. 26, 1920;

Application filed August 7, 1919. Serial No. 315,961.

To all whom it may concern Be it known that I, NORMAN 'HonAon IzoD, a subject of the King of Great Britain, residing at Samarai, in the Australian Territory of Papua, have invented anew and useful Improved Excavator for Fleshing Divided Cocoanuts, of which the following is a specification.

This invention refers to the removing of the meat or flesh from cocoa-nutsafter such nuts have been split or dividedand it has been specially devised in order to provide an excavator or excavating device or instru ment whereby such meat or flesh (to afterward form copra) may be rapidly and thorougl'ily removed from the halved or divided cocoa-nuts.

This improved excavator for fleshing divided cocoa-nuts consists of one or more flexible knives or blades arcuated from a rotary support to a point or points the center of rotation and preferably slightly helically set at the leading or cutting edge and whose spheroidal curvature is adapted to.

be expanded by pressure upon the point or points and upon withdrawal of such pressure to recover normal position and to facilitate and control this expansion the point or points of the blade or blades is or are preferably affixed to a crown piece slidable on a stem in or about the driving shaft of the rear rotary support. But'in order that this invention may be easily carried into effect the preferred practical adaption of same will now be described with reference to the drawings accompanying and forming part of this complete specification.

Figures 1 and 2 are longitudinal views at right angles to one another of this improved excavator for fleshing cocoa-nuts and Figs. 3, 4:, and 5 are transverse sectional views of same at lines 3-3 4---& and 55 respectively while Fig. 6 is an end view of the crown piece and Fig. 7 a similar view of the whole.

To a shaft 8 by means of a set screw 10 a head 11 is fastened in this case having three faces to each of which is aflixed by screws 12 a flexible knife or blade 13. In the shaft 8 crown piece 19 having wings 20 in a recess in each of which wingsand fastenedto it by rivets is the point of the blade 13 leaving a free; leading or cutting edge 14 to said blade.

7 Each flexible blade 13 extends forwardly from the head 11 approximately parallel with the axial line of the shaft 8 and slightly helically set thereto and then spreading or rather curving as a sector of an approximate spheroidal wall inclining and termi-" nating in a somewhat blind point at the center l i on an extension of said axial line where it is riveted to a wing 20 of the crown piece 19 as before mentioned.

The rotary head 11 being rotated by shaft- 8 the outer ends of the curved blades represent a rotating approximately spheroidal cage with cutting edges on the sectors thereof (being the blades) and these cutting edges excavate or remove from the concave half cocoa-nuts placed over the junctioning ends of the blades the flesh or meat thereon or therein. Pressure is applied externally of the half-nut as the diameter thereof requires the crown piece spindle slides in recess of extension 9 of shaft 8 and the bodies of the flexible blades 13 spheroidically expand to said diameter and practically clear all the flesh from the half-nut wall as ity is applied over and pushed against the outer end of the excavator and when the pressure is relieved the blades by their own elasticity slide the crown piece 19 outwardly and the blades take up normal position again.

What I claim as my invention, and desire to secure by Letters Patent is 1. In an excavator for fleshing divided cocoanuts a rotary flexible blade arcuate to the center of revolution and having its curvature expanded by pressure on its end.

2. An excavator for fleshing divide/deocoa-nuts including a rotary head and a plurality of flexible pointed blades, carried by the head arcuate to a common center of revolution, and forming sector walls of a spheroidal cage adapted to be expanded on pres-- sure being applied to the points of said blades.

3. An excavator for fleshing divided cocoa-nuts comprising a rotary head, a pluralityof flexible blades forming sector walls of a spheroidal cage, and having their back ends carried by the head, and a crown piece holding the forward pointed ends of said flexible blades, and With said head being arranged in an axial line and adapted to approach one another on pressure being applied to one of them. i i

4-. In an excavator for fleshing divided cocoanuts, a rotary flexible blade having a cutting edge and arcuate and tapered to its center of revolution, and adapted to have its curvature expanded by pressure on its outer end.

5. In an excavator for fieslnng divided cocoanuts, the combination with a rotary shaft, of a head fixed 0n the shaft and a plurality of flexible blades fixed to the head and having cutting edges and arcuate and tapered to their common center of revolu- 6. An excavator for fleshing divided 00- coa-nuts as claimed in claim 5 wherein the shaft isextended and provided With a recess, a stem slidable in the recess, and a crown piece fixed on the outer end of the stem, and having outer ends of the blades connected thereto.

In testimony whereof I have signed my name to this specification.
